[Innkeeping]

Description

Please include a summary of the changes and which component(s) are affected. Explain how your changes improve or modify the component's functionality within the Hyperfy ecosystem.

Adding a Docspane component that opens from Code Editor. The docs pull from a json that is created from the dev branch docs/ref api docs. It has a search feature. Closes when the inspect pane closes. It is draggable. It currently doesn't have a resize feature. But maybe when usePane includes this, we can add the capability.
